WINDMIIlL-OILING APPARATUS.

Specification of Letters Patent.

Patented Aug. 22, 1911.

Application ma January 17, 1911. serial-no. 804,006.

To all whom it may concern:

Be it known that I, GEORGE A. Dams, a citizen of the United States, residing at Green Bay, in the. county of Brown and State of Wisconsin, have invented a new and useful Apparatus known'and described hereinafter as a Windmill-Oiling Apparatus,

of whi ch the following is a specificatlon.

My invention consists of an apparatus for oiling the bearings of a windmill by forcing oil by means of a force pump and a pipe leading to the highest point of the windmill machinery and distributing the oil from that point through a swivel cap and an auxiliary reservoir to the various bearings by gravity.

In the accompanying drawing illustrative of the device Figure 1 represents a partial perspective view of the mechanism, and Fig. 2 a sectional View throughthe swivel cap and arm mounted on the upper end of the pump rod.

Similar numbers refer to similar parts in the several views.

1 represents the apexor swivel top of an ordinary pattern of a windmill tower. 'I

have represented as mounted upon' this a common form of windmill mechanism as best showing the application of my device though I propose to apply my device to any pattern of windmill in which the circular motion of the .wheel is made to impart a reciprocating motion to a vertical rod or shaft.

In the common form here shown, 2 is the frame, 3 the wheel shaft, 4 the driving pinion, 5 the counter shaft, 6 the crank gear, 7 the connecting rod, 8 the crosshead, 9 the pump rod, which is attached to the pump rod or shaftbelow.

My device consists of the following .attachments:10 is an oil reservoir, 11 a force pump attached thereto or used in connection therewith,- with check valves 13 and '14. 15

. is a flexible hose for attachment between pump and the oil conduit 16 which is attached to the pump rod or driving shaft,

and is connected with the pump rod 9 at 17.

In the ordinary pattern of windmill the pump rod 9 is a solid rod which I replace with a pipe, which I use as a continuation of the 011 pipe riser. I carry this pipe some distance above the top ofthe crank connection, and terminate it with a swivel cap 18 which is shown in perspective Fig. 1 and in section in Fig. 2. This swivel cap. con- 9 does not turn with the mechanism.

sists of a ferrule 19 in which the pump rod 9 turns, a packing ring 20, and half'ball 21 with a diaphragm 22 which fits the pump rod 9 tightly, and is attached thereto. Openings 23 are made in the outer portion of the diaphragm over'an oil groove 24 in the top of the ferrule. This groove is tapped at 25 for an oil feeder to the two connecting rod end bearings 26 and-27. The main outlet of the cap is at 28. A tight cap 29 closes the top of the swivel cap. From outlet 28 a pipe 30 in the form of an arm is led over and into an auxiliary oil reservoir '31 which is placed above the frame of the mill and at a higher point than any of the bearings of, same. From the bottom of this auxiliary oil reservoir 31v tubes 32 lead to the various bearings below. To reach bearing 27 a tube 33 leading from the swivel cap 18 is carried down to .center of bearing 26 into a little hopper 34 formed at-the top of a tube 35 leading to the bearing 27. Tube 35 is attached to the connecting rod 7. Pump rod The whole upper mechanism of the millhowever turns with the varying direction of the wind upon swivel 2. The arm 30 is placed high enough above and the drop of the end long enough so that the drop end will always be below the top of the auxiliary oil reservoir. This drop end will be led through an elongated hole in the cover of the auxiliary oil reservoir and the drop part of the arm striking the sides of the cover will cause the swivel cap to turn when the windmill head turns with the wind. The arm raises and lowers with respect to the auxiliary oil reservoir 31 with the reciprocating motion of the connectin rod 7 but the lower end being always inslde and below the cover of the auxiliary oil reservoir the oil is retained.

By means of the mechanism above de-' scribed oil is pumped from the loweroil reservoir to the highest point, a part de- What I claim as novel and desire to secure by Letters Patent .is:

'1. An oiling device for windmills comprising a reservoir,.an oil conduit, a swivel cap, an auxiliary reservoir and means for' to a portion of the bearings. device a hollow 2 distributing oil to a portion of the bearings from said auxiliary reservoir. 2. An oiling device for windmills comprising an oil conduit, a'hollow pump rod providing a continuation of said conduit, a swivel cap on the hollow 'pump rod, an auxiliary reservoir, a pip'e leading from the swivel cap to the auxiliary reservoir, means for forcing oil j through the oil conduit, meansv for distributing oil from the swivel cap .to a portion of the bearings, means vfor. distributing oilfrom the auxiliary reservoir" 3, In a windmill oiling pump rod, a swivel cap on said pump rod, means for forcing oil through said hollow pump rod, and means for delivering oil from the swivel cap to various bearings and an auxiliary reservolr as set forth.

4. In an 011mg devlce a hollow pump rod,

' a swivel cap on said pump rod, an auxiliary reservoir, and means for distributing oil 7 from the reservoir by gravity to the various bearings.

5'. In an oiling device a hollow pump rod, a swivel cap on said pump rod, means for distributing oil from the swivel cap to a portion of the bearings, means for delivering oil into an auxiliary reservoir as set forth. GEORGE A. DENIS.
